Most machine shops charge by the hour. Just bring in the spaces and tell them to mill them down .500" on the underside (not the side with the chamfer).

I've been going back and forth over the TM leveling kit. I can't decide if I want it or not. Heard some things about putting too much stress on the rack with the leveling kit installed. How hard was it to install since it just went on top of the strut now? Heard alot of people say installing the "old" kit was really hard because of the tension of compressing the springs. How long did it take you to install this kit?
